(CNN) -- Two children were injured Saturday in Arizona when a dust devil lifted a jumping castle about 15 feet into the air, blowing it across three lanes of traffic before flinging it to the ground, the Tucson Fire Department said.
The children, a boy and girl, were inside the jumping castle at the time and have since been taken to an area hospital. Their injuries are serious, but not life-threatening, said Tucson Fire Department spokeswoman Trish Tracy.
Officials responded to the incident at the corner of 11th Avenue and Speedway Boulevard around 2 p.m., she said.
Video from CNN affiliate KGUN shows investigators taking pictures of the deflated castle, which crashed in the median on Speedway.
Tracy said Saturday's incident was the second involving a jumping castle in Pima County this year.
